Timber glazing upgrades in Willington
Retrofit Double Glazing is one of those jobs in Willington where the survey decides everything. You will find mostly colliery terraces, Georgian Durham city stock and Pennine stone housing in this area, and it moves as it ages. The other factor is cold upland winters with heavy rainfall, which is why frost and saturation damage on unmaintained painted softwood is the most common reason people call us. Everything we do here comes back to reworking the rebate so a sealed unit fits without bulking the section.
Every job is measured on site first, because drawn sizes and built sizes are seldom the same. Tell us the problem rather than the solution and we will advise on both.
Local factor worth flagging early: Durham's cathedral setting carries World Heritage-level design scrutiny.

Do you take a deposit?
Not before the measured survey. A deposit is only requested once the survey is complete and you have approved the final schedule and price.
Do you work in hardwood or softwood?
Both. Engineered hardwood is the default where movement or exposure is a concern, and slow-grown softwood is often the better value choice for painted work in sheltered positions. We will tell you which we would specify and why.
Will the finish need maintaining?
A factory-applied microporous finish typically needs inspection every three to five years, sooner on exposed coastal elevations. Maintaining it is far cheaper than letting a coating fail and the timber take up water.
Do you fit, or supply only?
Both. Supply-only is common for trade and contractor clients. For private clients we usually recommend supply and fit, because responsibility for the fit and the finish then sits in one place.
What if the opening is out of square?
Most older openings are. The survey records the actual dimensions at several points and the unit is manufactured to suit, which is the main reason we survey rather than work from the sizes given over the phone.
